gstreamer mjpeg encoding don't work

[kingalione]

Hello I'm trying to stream a livestream to my iPhone via gstreamer.

My Pipeline on server side looks like this:

sudo gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw,width=3072,height=2048,framerate=15/1 ! videoconvert ! videoscale ! video/x-raw,width=600,height=400 ! jpegenc ! rtpjpegpay ! udpsink host=192.168.178.92 port=5000

Where 192.168.178.92 is the IP of the iPhone. But somehow I'm always getting this error here:

WARNING: from element /GstPipeline:pipeline0/GstVideoScale:videoscale0: Internal GStreamer error: code not implemented. Please file a bug at http://bugzilla.gnome.org/enter_bug.cgi?product=GStreamer. Additional debug info: gstvideofilter.c(291): gst_video_filter_transform (): /GstPipeline:pipeline0/GstVideoScale:videoscale0: invalid video buffer received

So what is the problem here? I've oriented myself to this tutorial here: http://www.einarsundgren.se/gstreamer-basic-real-time-streaming-tutorial/

This looks like a bug in some element or video4linux driver somewhere. 

Please could you file a bug in bugzilla?

We'll probably need a GST_DEBUG=*:6 log as well.
